OILERQ SPECIFICATION forming part of Letters Patent No 296,047, datedApril 1, 188- Application filed February 6, 1884. (N0 model.)

Be it known that I, JOHN S. PARK, of Rockport, in the county of Spencerand State of Indiana, have invented a new and Improved Oiler, of whichthe following is a full, clear, and exact description.

The object of my invention is to provide a simple, inexpensive, andeffective device for oiling the crosshead guides of steam-engines, moreparticularly; but the invention is applicable also to oiling the guidesof other reciprocating parts of machinery.

The invention consists in an oiler having pivoted oiling-heads carryingoil cups or reservoirs, and a weighted stem to throw the oil: ing andwiping heads into contact with the friction-surfaces of the cross-headguides by the inertia and momentum of the parts on reversal of themotion at the limit of the stroke of the cross-head in either direction.

The invention consists, also, in certaindetails of construction andcombinations of parts of the device to adapt it to serve either withsingle or double cross-head guides, all as here inafter fully describedand claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figurel is a side elevation of my improvement as applied to thesingle-bar cross-head guide of alocomotive stearn-engine. Fig. 2 is aplan view of the same in part; and Fig. 3 is y a side elevation, partlybroken away, of a modification' of the improvement, and as applied to adouble parallelbar cross-head guide.

, Referring first to Figs. 1 and 2 of the draw ings, A is thecross-head;B, the bar or guide on which the cross-headtravels back and forth. G isthepiston-rod connecting the cross-head with the piston in the cylinderD, and Eis the connecting-rod leading to the engine-crank. All theseparts may have any approved construction.

On any suitable base-plate, F, I fix three standards or posts, G G G, Gbeing the (zen-- ter post, to which is pivoted the head H, which has asegment of gear-teeth, h, at each end, and a central stem, H, fixed atright angles to the head .11, and carrying a weight, H which preferablyis adjustable along the stem, and may be held, when adj usted, by aset-screw, c.

On each side post, G, I pivot at 9 an arm, I,

which carries at one end a segn'lentplate, I,

having gear-teeth z, meshing with the teeth h of the head H, and at theoutside downwardlybent portion of the arm I is fined a plate, J, havinga wiper or cushion, j, of any suitable soft fabric.-such as sponge,felt, &e.secured to its under side, to receive and distribute over theface of the guide B the oil fedlto it through a passage in the plate Jfrom an oil-cup, K, of any suitable kind, carried on the back of theplate. The gears h t are interxneshed, so that a rocking of the weightedstem H to either side of a vertical line will raise one oftheoiling-heads J j from and lower the opposite one to the guide-bar B.

In operation, as the cross-head A moves inward toward the cylinder D,the stem H will lie over to the left of a vertical line, and theright-hand oilerhead J j will bear on the guide B in advance of thecross-head A or its brass a, and after completion of the inward stroke,and on reversing for the outward movement, the inertia of the weightedstein H, together with the forward momentum of the cross-head in itsoutward stroke, will cause the stem H to shift over quickly to the rightof the vertical line and lift the inward oiler-head J j and lower theouter head J j upon the guide B and in advance of the movingcross-head,which are the positions of the parts shown in the drawings.At the extreme limit of the outward stroke, and on reversal for theinward stroke, the stem H will be shifted to the left, and theright-hand oiler will bear on the guide B in front of the cross-head, asfirst described, and these operations will be continued with the travelof the cross-head, the opposite heads 0 J j bearing always on the guideB in advance of the cross-head. The oiling-heads not only feed oil tothe upper face of the guide, but act also-to wipe from it any dust orgrit, which would, if not removed, unduly wear the fric- 5tion-surfaces. a

I have shownthe oiler base-plate F slotted at f, so as to pass beneaththe heads of the nuts d, used to fasten the top brass, a, and take upthe wear of the brasses; but the oiler may be held to the cross-head inany other suitable manner. I

In the modification shown in Fig. 3, in which I apply the same principleof rocking the opposite oiling-heads into contact with the guide-bars bythe inertia and momentum of the parts on the reversals of stroke of thecross-head, I pivot to both sides of the crosshead A a four-armed orsuitable head, G

made hollow to communicate with an oil-cup,

K held thereon, and deliver the oil from the cup and through oppositehollow arms or tubes 1 to perforated oiling-heads J having oil-absorbingwipers suitably fixed around them, and entered by bending the tubes 1between the parallel side guide-bars, a a, and the stem H is weightedadjustably at H, sufficiently to 'overbalance the oil-cup K to eitherside as the strokes of the crosshead are reversed. In the drawings thecross-head is moving to the left hand on the outward stroke, forexample, and the left-hand head J rests upon the lower bar a to wipe andoil it, and the opposite or right-hand head J j rises against the upperbar a to wipe and oil it, and on the reverse or rearward stroke theright-hand head J 2 j will oil the lower bar a in advance of thecrosshead,while the left-hand head will oil the upper bar, as willreadily be understood.

The oil-cups shown may be substituted by recesses in the oiler-heads,forming'reservoirs for the oil, and connecting by suitable passages withthc wipers or pads of the heads.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. An oiler for the guides of engine crossheads and other reciprocatingparts of machinery, constructed with apair of opposite pivotedoiling-heads carrying or connected with an oil cup or cups, and having aweighted stem adapted to be thrown to either side of a vertical line forbringing the oiling-heads in con tact with the guide bar or bars by theinertia and momentum of the parts on reversal of the motion at thelimits of the stroke of the crosshead in either direction,substantiallyas shownand described.

2. In an oiler, the combination, with a weighted stem pivoted to-thereciprocating cross-head, of an oiling-head actuated by the swing of thestem to either side, so as to bear the oiling-head on the cross-headguide in advance of the moving cross-head, substantially as shown anddescribed.

3. The combination, in an oiler, and with the reciprocating cross-headA. and guide B, of the pivoted head H, carrying a weighted stem, H, andpivoted arms I, swung by the stem and provided with oil cups orreservoirs and absorbent wipers J j,receiving the oil and distributingiton the guide, substantially as shown and described.

4. The combination, with the cross-head A and its side guides, a a, ofthe pivoted heads G, carrying oil cups or reservoirs and weighted stem Hthe hollow arms P, and the oilerheads J 2 j, working between the guidesa a, substantially as shown and described.
